STMicroelectronics STM32F429ZIT6 ARM Cortex-M4 Microcontroller, 144-pin LQFP

The STMicroelectronics STM32F429ZIT6 ARM Cortex-M4 Microcontroller is a high-performance 32-bit device from the STM32F4 Series, built around an ARM Cortex-M4 core with a floating-point unit (FPU). It is engineered for demanding applications and provides 2MB of program memory and 256KB of RAM.

Key Features

• ART Accelerator and Chrom-ART Accelerator to optimise execution from flash memory and enhance graphics performance
• Full set of DSP instructions and a Memory Protection Unit (MPU) for enhanced application security
• FMC (Flexible Memory Controller) with SDRAM and TFT support
• Three 12-bit ADCs (24 channels), two DACs and a low-power RTC
• Twelve 16-bit timers (two for PWM motor control) and two 32-bit timers

Connectivity and Interfaces

The device supports CAN, I2C, I2S, SPI, UART, USART and USB communication. It features an LCD parallel interface (8080/6800 modes) and an 8- to 14-bit parallel camera interface capable of speeds up to 54 Mbytes/s. Additional system features include a true random number generator, a CRC calculation unit and a 96-bit unique ID.

Power, Reliability and Debug

• Operating supply range of 1.8V to 3.6V
• Industrial temperature range from -40°C to +85°C
• Power management features: POR, PDR, PVD and BOR
• Debug capabilities via SWD and JTAG interfaces, plus a Cortex-M4 Trace Macrocell

Package and Dimensions

The microcontroller is housed in a 144-pin LQFP surface-mount package and provides 114 I/O pins. Dimensions are 3.3 (width) x 1.5 (depth) x 4.3 (height), with a weight of 5.575 gm.

The combination of processing, memory, analogue, and connectivity features makes this microcontroller suitable for industrial, user interface, and motor control applications.
